2黑龙江水稻的熟制为( )

A.一年一熟B.一年两熟C.两年三熟D.一年三熟

【答案】

1D

2A

【解析】

影响农业区位的主要因素:自然条件:气候、水源、土壤、地形;社会经济条件:市场、交通运输、政府政策、劳动力、土地价格、资金、管理;技术条件:冷藏、良种、化肥、机械。一年中≥10℃的积温,又称活动积温,是把≥10℃持续期内,每天的日平均气温加起来,得到的温度总和。是研究温度与生物有机体发育速度之间关系的一种指标,从强度和作用时间两个方面表示温度对生物有机体生长发育的影响。积温值越大,作物的生长期越长,我国温度带的划分主要指标就是看≥10℃的积温。

1

黑龙江省位于我国的东北地区,农业技术水平,黑土广布,土壤肥沃,属于温带季风气候,雨热同期,气温低,冬季病虫害少,农药使用量少,由于纬度高,热量条件差,所以生长期长,一年一熟,有利于营养物质积累,因此,黑龙江大米颗粒饱满、口感好,水稻品质优良与劳动力资源丰富程度无关。故选:D

2

黑龙江省位于我国的东北地区,属于温带季风气候,在中温带,由于纬度高,气温低,热量条件差,所以生长期长,气温条件只能满足农作物的熟制为一年一熟。故选:A。

本题主要考查东北地区的农业,理解解答即可。
